Circular die is a mold made by installing blades on curved wooden boards. The processing technology is complex, and the following precautions should be taken:
(1) The circular die used for die-cutting cigarette packs should have a machining accuracy within ± 0.07mm for product die-cutting error; For magnetic circular die cutters, as they usually use several die-cutting knives to simultaneously cut different parts of the product on a single line, the processing accuracy should be within ± 0.03mm of the product die-cutting error.
(2) After processing and forming, the width of the cutting edge of the circular die is 0.02-0.05mm and the height is 1.0-1.5mm. In order to strengthen the control of its deformation during processing, it is basically required to use superhard processing methods, which puts high demands on the comprehensive processing ability of technicians, such as their understanding of the characteristics and processing equipment of the circular die cutter, as well as their control of the hardness, toughness, and material deformation of the tool during later heat treatment.
The improvement of this comprehensive processing capability is the main factor determining the final forming quality of the circular die.
(3) Due to the constantly changing die-cutting graphics of cigarette packs, each round die cutter is a brand new product, which places high demands on the design ability, process adaptability, and personnel quality of the round die cutter manufacturing company.
